In The Original Series in the 60s, people had no idea what the future would look like or what technology would look like. In one of the early episodes, they had a paper print out machine on the bridge that looked like a fax machine, which was considered futuristic in the 1960s.
Like the example of the Enterprise fax machine, what technology or system do you think are we displaying in the current Star Trek shows that will show how dated we will become in the future?
I think the opposite. Economies of scale would make it better to build HUGE. Kilometer long ships that can do everything you need with tons of redundancy. This means whole families can come along. Everyone has jobs, and every job is covered.
